براغي رأس مقبس بنقطة كوب HOLO-KROME 32124 1/4-20 X 3/4" | فولاد سبائك بأكسيد أسود حراري (100 / عبوة)

These cup point set screws bite into shafts much better than the standard cone point ones I've used before. The black oxide finish on the alloy steel seems clean and consistent across all 100 pieces, which saved me a trip to the hardware store.

I needed a full pack of these for a few repair jobs and the black oxide finish on every single one looks consistent and clean. The hex socket drive made installation quick with a standard Allen key.

These cup point set screws bit into the shaft exactly as needed with no slipping after tightening. The black oxide finish feels durable and the threads were clean on every single one in the package.
